Runs in SDSS with slightly different survey coordinates

A few runs in the SDSS were taken with the telescope parked and scanning along the equator at the sidereal rate. These runs have a different node and inclination from the survey's default node of 95° and inclination increasing in steps of 2.5° from stripe to stripe.

To obtain the correct astrometrical transformations for these runs, you need to use the node/inclination given in the fits header of the tsField files, instead of the node and inclination used in the equations given in the coordinates section of the EDR paper.
